    摘要： A photosensitive member having at least two electrically operative layers is disclosed. The first layer comprises a photoconductive layer which is capable of photogenerating holes and injecting photogenerated holes into a contiguous charge transport layer. The charge transport layer comprises an electrically inactive organic resinous material containing from about 10 to about 75 percent by weight of: ##STR1## R.sub.1 is selected from the group consisting of hydrogen (ortho) CH.sub.3, (meta) CH.sub.3, (para) CH.sub.3, and R.sub.2 is selected from the group consisting of hydrogen, (ortho) CH.sub.3, (meta) CH.sub.3, and (para) CH.sub.3. The charge transport layer while substantially non-absorbing in the spectral region of intended use is "active" in that it allows injection of photogenerated holes from the photoconductive layer, and allows these holes to be transported through the charge transport layer. This structure may be imaged in the conventional xerographic mode which usually includes charging, exposure to light and development.

    摘要： A photosensitive member having at least two electrically operative layers is disclosed. The first layer comprises a photoconductive layer which is capable of photogenerating holes and injecting photogenerated holes into a contiguous charge transport layer. The charge transport layer comprises an electrically inactive organic resinous material containing from about 15 to about 75 percent by weight of N,N'-diphenyl-N,N'-bis(phenylmethyl)-[1,1'-biphenyl]-4,4'-diamine. The charge transport layer while substantially non-absorbing in the spectral region of intended use is "active" in that it allows injection of photogenerated holes from the photoconductive layer, and allows these holes to be transported through the charge transport layer. This structure may be imaged in the conventional xerographic mode which usually includes charging, exposure to light and development.

    摘要： A photosensitive member having at least two electrically operative layers is disclosed. The first layer comprises an electrically conductive layer. The second layer comprises a charge transport layer. The third layer is a photoconductive layer contiguous with the transport layer. The photoconductive layer is capable of photogenerating and injecting photogenerated holes into the contiguous or adjacent electrically active part. The electrically active material comprises a polycarbonate resin material having dispersed therein from about 25 to 75 percent by weight of one or more compounds having the general formula: ##STR1## wherein X is selected from the group consisting of an alkyl group having from 1 to about 4 carbon atoms (e.g. methyl, ethyl, propyl, butyl, etc.) and chlorine in the ortho, meta or para position. This structure may be imaged in the conventional xerographic mode which usually includes charging, exposure to light and development.
